Abby and Gibbs in “Forced Entry”

Abby

Jeremy Davison has no criminal record, Gibbs. He's a civilian, he has no ties to the military, his prints don't match any open casefiles. The boy doesn't even have a speeding ticket. I mean, we're talking cleaner than clean. Whiter than white. You could put him in the lineup with snow, snow is going to jail.

Gibbs

Or it just means he's never been caught.

Abby

[resignedly] Or it just means he was never caught.
